I am running Jetpack 4.1 on the Xavier and having troubles with PCIe.
The device I am using shows link activation for only a second or two on the initial boot of the Xavier then it goes down. The boot log doesn’t seem to have anything unusual as far as I can tell. I have tried the Xavier with some more common PCIe devices (Intel X520) which work as expected. The device in question is fine on x86 Ubuntu Linux.
What are the next steps to take to debug why this device does not stay up?
